Visible light photodegradation of organics over VYO composite catalyst
This paper presents a visible-light driven photocatalyst, VYO composite, which was synthesized by doping YVO4 with V2O5. The catalytic testing results indicate that the photocatalyst shows high activity for photodegradation of acetone under both UV and visible light. The highest acetone conversion was obtained over V1.5Y1Ox composite catalyst. By doping a small amount of metal Pt the photocatalytic efficiency of the catalyst could be promoted further. It was also proved to be efficient for the photodegradation of methanol, ethanol, 2-propanol, and benzene. The physical and photophysical properties of the VYO composites were characterized by BET, XRD, FT-IR. Raman, UV-vis spectra, and photoluminescence spectra, respectively. On the basis of the investigation results, the high photocatalytic activity might be attributed to the coupling effect between YVO4 and V2O5. Crown Copyright (C) 2009 Published by Elsevier B.V.
